2016 two CD release. The Astonishing is undisputedly the most ambitious undertaking by a band whose cerebral compositions already define the vanguard of progressive hard rock. The Astonishing is enriched exponentially by the integration of a real orchestra and choir, arranged by conductor David Campbell, whose work graces over 450 gold and platinum albums, including watershed releases from Adele, Justin Timberlake, Linkin Park, Evanescence, Beyoncé, and his son, Beck. The Astonishing was produced by John Petrucci with engineering and mixing by Richard Chycki, whose resume includes work with Rush, Aerosmith, and Mick Jagger. Other organic sounds are more abundant than at any point in the band's history, with Jordan Rudess in particular relishing the tones from a grand piano and Hammond organ. Like Tommy or The Wall, the songs on The Astonishing work as both singular compositions and overall story components. Writing the music as a duo, Petrucci and Rudess venture into unexplored corners of their sound without sacrificing their musical identity.
